Dr. Mindbender

Dr. Mindbender is a fictional character from the 1980s G.I. Joe: A Real American Hero toyline, comics, and animated series. He is a scientist who works for the fictional terrorist organization COBRA.

HISTORY
Dr. Bender was at one time a peace-loving orthodontist. He built a machine to relieve dental pain, using electric brainwave stimulation. Unfortunately he tested it on himself, and when it went haywire, he became hateful, deceitful and vain. Dr. Mindbender abandoned his practice and joined forces with Cobra, devoting all his time to perfecting his digital brain-scrambling. He is a master of mind control and interrogation, but his expertise also includes genetics, cloning, dentistry, and some cybernetics.

Doctor Mindbender is first shown in the G.I. Joe episode "No Place Like Springfield Part 2" voiced by Brian Cummings. Shipwreck runs through Cobra's base and knocks a vial of chemicals out of the doctor's hand. They land on his head, causing him to lose his hair. Mindbender is Cobra's chief interrogator and science officer. He hates Cobra Commander(who calls him "Fender-Bender"). In "Arise Serpentor Arise", he collaborates with Destro and Tomax and Xamot in a plot to obtain DNA samples of the best militaristic minds in history, because he feels Cobra needs a leader that can inspire courage in its cowardly troops. This results in the creation of Serpentor. Doctor Mindbender is easily Serpentor's most loyal member of Cobra's High command (and as such Serpentor trusted Doctor Mindbender the most out of the Cobra High Command, even being exceptionally lenient if a mission's failure is Mindbender's fault), but there are times when he considers the monarch to be a "spoiled brat".

G.I. Joe: The Movie
In G.I. Joe: The Movie, it is revealed that the idea to create Serpentor was planted in Mindbender's brain by Golobulus(the leader of Cobra-La) using the "Psychic Motivator". Doctor Mindbender appears outraged by this, as he had thought of Serpentor as his own creation, but he quickly falls into line and begins serving Cobra-La. Doctor Mindbender is present in the final battle between Cobra, Cobra-La and the Joes.
